Some Cars from I would like IN GTA SA

razr2010

I have been searching this forum for about a week now, and i have not been able to find what i want. There are a couple of cars that i would like to have in GTA San Andreas. The cars are: BMW M3 GTR from NFS Carbon, Dodge Viper, BMW M5, and the Mclaren F1. I am relatively new to modding GTA, so i don't know if cars are replaced or if they are added as separate cars. I would prefer them to be separate if it is possible, but if not, replacing others is fine.

Cars:

BMW M3 GTR:Just search "NFS Carbon BMW Pictures" in Google images.

For all the others, if you don't know what they look like, you can just search them up in Google images
